well my question is why is it a problem for clearance if that crush section is really for epa standards.....other than the fact that it's for both clearance and epa standards.....so those jeep engineers hi-fived eachother for hitting two birds with one stone.....more like whacking the exhaust with a stone and call it a day haha. anyway thanks for the info.
would like to see if I candy reroute the pipe myself. make it easy not having to bother with the exhaust shops around here.

What would be interesting is to see the "engineering/thinking" that went into "placing a restriction ahead of the cat will make the cat heat up faster".
Seems like things ahead of a exhaust restriction would heat up faster and things after would heat up slower.

Slowing down the exhaust flow heats it up. They also had a lesser "crush" before the converter where the pipe goes over the crossmember.

HC's are just unburnt fuel. Some from the space above the top ring and the top of the piston, some from a thin layer right against metal that isn't as hot. The "air pumps" in the old days were to provide oxygen into the exhaust so it could burn.

Ok that's good news... Is there a Renix header then? And then I can upgrade the down pipe at the same time? To 2.50?
